New gene regulation mechanism discovered
... stimulated by various stress conditions including wound
healing and viral infection. "That told us that when cells are stressed, maybe the atypical messenger RNA is released from the nucleus, exported to the cytoplasm, and translated into protein, thus circumventing the time-consuming process of producing...
Plant wounds trigger bacteria
ITHACA, N.Y. -- How does a wound

Scientists unpick genetics of first 15 minutes of life
...ists found that the pro-nucleus in ssame mutant is wound
into a tight ball that could not interact with its female counterpart, the egg pro-nucleus. This showed that there was a problem with the re-packaging process in the ssame mutant. The researchers looked at the genetic makeup of the ssame mutant and i...
Polymer gel can block toxic leakage problem in gene therapy
...he form of a polymer compound already employed for wound
healing and for drug and gene delivery. After being mixed with a gene-bearing virus, this compound -- called poloxamer 407 -- undergoes a temporary phase change as its stiffens from a liquid to a gel state when warmed to body temperature, that study ...
Einstein scientists discover how protein crucial for motion is synthesised at the right place in the cell

infections. This is the first time that Aeromonas has been detected in the Katrina floodwaters, Presley says. Animal tissues sampled, including dead snakes and an alligator, also contained multiple metals and pesticides, but these levels were genera...
Cancer scientists call for a large-scale human epigenome project

UCSD study finds anthrax toxins also harmful to fruit flies
...pted by LF treatment is similar mechanistically to wound
healing, which is mediated by the same signaling pathway in humans. The EF toxin is also lethal when applied to fly larvae and can cause severe malformation in the wings of adult fruit flies--an effect that can also be understood as an interruption o...
Aging cells, aging body: Fresh evidence for a connection

healing, weakened immune system response and age-related diseases such as cancer. "There is good evidence that senescent cells are not benign," Sedivy said. "But until now, no one has been able to confirm that they exist in appreciable numbers in old...
Heparin prepared synthetically could replace animal-derived drug
